GPA Scale — the 4.0 grade chart
Every letter grade with its grade points and percentage, on the standard 4.0 scale. Look up any grade in a tap.
The standard 4.0 GPA scale
The 4.0 scale is the grading system used by most US high schools and colleges. Each letter grade is worth a fixed number of grade points, and your GPA is the credit-weighted average of those points across your classes. Pluses and minuses move the value up or down by 0.3, so a B+ is 3.3 and a B− is 2.7.
| Letter | GPA points | Percentage |
|---|
The weighted GPA scale
Many schools use a weighted scale that rewards harder classes with bonus grade points — usually +0.5 for Honors classes and +1.0 for AP or IB classes. On that scale an A is worth 4.5 in an Honors class and 5.0 in an AP class, which is why weighted GPAs can rise above 4.0.
| Letter | Regular | Honors | AP / IB |
|---|---|---|---|
| A | 4.0 | 4.5 | 5.0 |
| B | 3.0 | 3.5 | 4.0 |
| C | 2.0 | 2.5 | 3.0 |
| D | 1.0 | 1.5 | 2.0 |
| F | 0.0 | 0.0 | 0.0 |
Try it yourself with the weighted GPA calculator, which applies these bonuses automatically and shows your weighted and unweighted GPA together.
A note on the 4.3 scale and A+
Not every school treats an A+ the same. On the most common unweighted scale, an A+ is capped at 4.0 — identical to an A — so a perfect transcript maxes out at 4.0. A minority of schools use a 4.3 scale that gives an A+ its own value of 4.3. Because of this, always check how your own school counts an A+ before comparing GPAs.
GPA scales around the world
The 4.0 scale is not universal. India commonly uses a 10-point CGPA system, Europe uses ECTS grades from A to F alongside local marks, and the UK classifies degrees into first, upper-second, lower-second and third-class honours. If you are converting a GPA for an application abroad, use the GPA to percentage converter as a starting point, and confirm the exact mapping the receiving institution expects — conversions between systems are always approximate.
